WIMPs

All WIMPs arise from work done at PARC. They first invented the GUI and then invented the pointing device that "enabled" that GUI - i.e. the mouse. Their version went on to become the X11R3 standard that was used on a lot of early PCs/microcomputers by those who were bothered to "fit" the X11 free source code into their flavour of x86 unix !!

As mentioned above, Apollo, Sun and others used various flavours of the X11R3 on their systems and was highly sought after by those who had to work in graphics !!
